DISCRIM accessory Knob ?

[pinenut]

Hey folks, does anyone use this knob? Know where I can get one?

Thanks!

Well, in case anyone was wondering... I did find out that someone who'd frequented another forum several years ago, made a few of those knobs. I did message that person but don't expect to get a response, as it looks like he last posted there in 2010.

Since I liked the idea and thought it would be so much nicer to thumb the disc comfortably, I decided to make my own. Those little 4" Chinese lathes are perfect for just such a project, and I cranked this knob out in the garage after a short time. Not as fancy as the other guy's, but it seems to work great! Tip of my thumb fits right into the hole, and I can smoothly spin it from all-metal, all the way round to max disc. I can see my setting right through the hole (in case I need to look). Perfect!

Someone needs to CNC a batch of these for the Tesoro thumbers... ^_^

Ahh, like a suicide knob but different.

Very nifty, and I'm sure will be useful. If only I had a 3D printer...

Would be even better, made from good plastic (Delrin, Nylon, etc.). A 3D printer would be awesome... Need to check those out!

Here's one more pic of it polished up.
Just a bit of blue LocTite on the setscrew. Added a 1/4" O-ring and a teensy dab of silicone grease between O-ring and pot lock nut, so it's super smooth with just a bit of drag. Still need to O-ring the other pots.

Only thing I don't like about this knob, is that it gets in the way of the on/sensitivity, but I wanted to be able to thumb the edge of the knob as well as the thumb hole, so I think I'll leave it as is. May make the next one as just a lever with thumb hole, that way the on/sensitivity will be more accessable... Anyway:

I didn't know you had to change the DISC. that often.

Maybe you don't... I hunt in lots of trash. When I get a good sounding target at a disc setting below nickel, I can thumb the disc up & down to see if it's still sounding solid, or where it's breaking up. Gives me an idea if if it's a nickel, pull tab, zinc or better. Not always accurate, but I find it helpful. Of course, I could just set disc at zinc and dig whatever x's small but has a solid beep. Where's the fun in that? ^_^

I'm going to make a lighter, lever-arm type to try out. Got to thinking that this knob I made, though seemingly quite functional, gets in the way of the knob above too much, weighs more than it should, and would be better non-metallic. What the heck; keeps me busy on days I don't go detecting. ^_^

I understand now and it makes sense-----------------just didn't understand when I first read it. The knob is cool.

My latest revision; lighter, less noticeable and more leverage. Doesn't block access to on/sensitivity as much. It's very smooth and works well.

One advantage of having an all metal switch versus the AM/disc knob is the capability to hunt in all metal and toggle to a preset disc quickly to see whether the target is above the disc setting. Even better on detectors with 2 disc settings like the Tejon.

Which is why I'm really liking my Eldorado. The Vaquero is also pretty easy to thumb from all metal to whatever disc I choose, with this knob. Not sure which detector I like better, Eldo or Vaquero, though Eldo has the nicer tone. Both work very well. ^_^

 

[luvsdux]

I agree. My Eldorado will be in my arsenal until one of us dies.

All very interesting. I have found that I have no issues what so ever with the stock knob and I thumb it a lot and can see the face plate and were the pointer is as targets disc out. The bigger round knobs would not be for me. I do like the knob with the pointer made out of carbon fiber but would want it a little shorter not so close to the foam on the handle when turned down into the foil & iron ranges.

Very very innovative ideas for sure and I can see how it would make the task of thumbing the knob more easy for some, great job. I always like how innovative folks can be to address an issues for there needs.

Happy Hunting,
